SAFETY RAZOR.

Application filed August 6, 1920. Serial No. 401,648.

To all'whom iii-"mag concern:

Be it known that I, LEON M. BUYUKAS, a subject of the King of Greece,and a resident of Grantwood, county of Bergen, and State of New Jersey,have invented certain new and useful Improvements in Safety Razors,

set forth in the following specification.

This invention relates to safety razors. The object of the invention isto provide a structure which shall be compact, simple, convenient foruse and at the same time, one in which all parts of the blade-holdingstructure are inter-connected to form an integral whole, even when thestructure is opened for the removal of the blade and with all the partsso arranged that the blade contacting surfaces are free fromobstructions so as to permit of ready cleansing, particularly for theremoval of rust stains.

More generally the object of the invention is to improve safety razorsof the type employing a flexible blade.

The above will be pointed out more particularly in the accompanyingclaims which are directed to the illustrative embodiment of theinvention, described in the following specification in connection withthe accompanying drawings, which form a part hereof, and in whichdrawings like characters designate corresponding parts in the severalfigures.

In the drawings, Fig. 1 is a left side elevation of the assembledstructure;

Fig. 2 is a front elevation of the assembled structure;

Fig. 3 is a right side elevation;

Fig. 4 is a plan view of the structure with the blade-holder open;

5 is a cross section of the assembled structure;

Fig. 6 is a plan view of the assembled structure ShOWiIlg thebladeclamped in position;

Fig. 7 is a section through VII VII of Fig. 6; and

Fig. 8 is a plan view of the blade employed.

A guard member A of substantially rectangular outline is arranged to bemounted on any suitable handle 1, detachably connectable therewith asthrough the means of the threaded stud 2; The blade engaging face 3 ofthe guard member A is preferably cylindrically convex, as is bestindicated in Figs. 1, 3 and 7, although these figures show the surface3, conforming to the shape of a line a smooth curved cylindricalsurface, it is to be understood that the expressions cylindrically andcylindrical in this specification are use to denote such a surface as isgenerated by an element moving parallel to itself and following either acurved line or the sides of an angle or a combination, lines and curves.The desired functioning shape for the surface 3 is such that a flexibleblade B mounted upon said surface 3 may be flexed or dished from itscentral line downward at both edges 5 and 6 :so that the edges 5 and 6approach the guard fingers7 and 8 which form the side terminal'edges ofthe guard member. A.

A clamping blade holder C of a length to span the blade B and the guardA and having a concave cylindrical under surface 9 .to. fit over thesurface 3 and for direct engagement with the blade B is suitably hingedat one end to the guard A. A preferred embodiment for the hinging is alink 10, hinged to the cars 11 of the guard A by hinge pin 12, and tothe blade holder C by the hinge pin 13, secured in the ears 14. By thisarrangement the link 10 is free to swing in the notches 15 and 16. Anotch 17, symmetrically positioned and otherwise similar to notch 15 issymmetrically hinged to the other end of guard member A A link 18 hashinged to it, by hinge pin 19 a double cam 20, operable by a thumb piece21,'while the link 18 itself is hinged to ears 22 straddling notch 16 onthe blade holder C by the hinge pin 23. The pins 12, 13 and 23, itshould be noted, are located sufficiently back from the blade engagingsurfaces 9 and 3 so that the links 10 and 18 may be swung completelyclear of these surfaces, as indicated in Fig. 4, so that a brush orcloth may be wiped over these surfaces to remove all rust stains withoutencountering any obstructions while, at the same time, the links 10 and18 may serve as positioning means for the blade B- by cooperationtherewith through the notches 24c and 25. So far as the structure of theguard and clamping member is concerned, they are both free from allobstructions to interfere with cleansing by a flat brush or polisher.The blade B positioned upon the guard A so that its notches 24 and 25correspond in position with the notches 15 and 17, may be clamped inposition by swinging the holder C up and overthe'blade. The link 18 ispressed into the notches l7 and 25 while the link 10 enters the notches15 and 24, serving to canter the blade B. A manipulation of the fingerpiece 21 serves to operate the cam 20 to clamp the blade holder C so asto flex the blade B and hold it firmly upon the guard member A.

It should be noted that even when the structure is opened, to remove theblade, the guard C is held fixedly assembled to the guard A by thelink-10 as likewise are all the other parts. This prevents the loss of apart in the use of the structure. Furthermore, the links 10 and 18,which cooperate with the blade B in the notches 24 and 25 forpositioning the blade, are readily swung clear of the cylindricalblade-engaging surfaces 9 and 3 and there are no projecting pins orposts otherwise to obstruct the wiping of these surfaces.

What I claim and desire to secure by United States Letters Patent is:

A safety razor comprising a guard member having a cylindricalblade-engaging surface free from obstructions to prevent cleaning; ablade holder for ing and binding a blade upon said guard member having asurface configuration complementary to said cylindrical clamp- 25blade-engaging surface of said guard member; a hinge link hinged at oneend to said serving as means for positioning a blade;

and a clamping hinge link for connecting the other ends of said guardmember and blade holder being hinged to the end of one of said membersto swing clear of its bladee'ngaging surface and beingprovided withdisengageable clamping means for the end of the other said member andserving, when in operative position, as means for positioninp; a blade.

In witness whereof I have signed my name to this specification, this 2ndday of August,

L. M. BUYUKA S.
